Title: Transition coupling
IPC: B61G5/04
Filed: 1958-10-08
Abstract: 895,047. Railway vehicle transitional type couplers. AMERICAN STEEL FOUNDRIES. Oct. 8, 1958 [May 19, 1958], No. 32142/58. Class 103(5). A transitional coupling device connecting an automatic coupler 30 and a hook coupler 42, comprises a take-up link 22 having side plates 32 mounted on chain link trunnions 38 provided with knurled knob handles 40, a trunnion 34 adapted to engage the hook coupler 42, a tie bar 36 between the plates 32, and links connecting the device to lugs 24, 26 on the automatic coupler 30. The centre line B, Fig. 4, of the trunnions 38 is below the centre line A of the trunnion 34 when the device is coupled up. In operation, the take-up link 22 is dropped into the hook coupler 42 and is held there by portion of the side plates 32 overlapping the sides of the hook. In this position the links connecting with the coupler 30 are slack. The take-up link 22 is then manually rotated in a clockwise direction as viewed in Fig. 4, about the axis A of the trunnion 34 seated in the hook 42 so that the side plates 32 are swung to a position in which the tie bar 36 abuts the hook 42 and prevents further clockwise rotation. In the latter position the slack in the links is substantially taken up, due to the eccentric rotation of the axis B of the chain trunnions 38 about the axis A, and the centre line B and the direction of any draughtload C is below the centre line A. The take-up link 22 may be rotated anticlockwise to a slack position, shown in the upper phantom line in Fig. 4, the link 22 because of its own weight and the weight of the chain links being swung clear to the lower phantom position when buffing occurs.

Title: Signal-translating system for color-television receiver
IPC: H04N11/14
Filed: 1954-11-11
Abstract: 752,544. Colour television. HAZELTINE CORPORATION. Nov. 11, 1954 [Jan. 8, 1954], No. 32687/54. Class 40 (3). In a colour television receiver for use with a transmission comprising a luminance signal and a chrominance sub-carrier, the D.C. component is stabilized by means of a single rectifier 16 which receives the luminance signal with the synchronizing component in the positive direction on its grid from directly-coupled amplifier 13 and is rendered conducting during the synchronizing pulse interval by anode pulses applied from the line scan circuit 19 through transformer 33. The potential developed across the cathode time-constant circuit 29, 30, which is several times the period of the synchronizing pulses, varies in accordance with the peak amplitude of the synchronizing pulses and selected portions of the potential are taken from tappings on potentiometers 31g-31b and combined with the colour difference signals appear. ing at the output of chrominance signal detectors 40g-40r. Potential changes corresponding to those appearing across the cathode circuit but of opposite polarity appear across anode circuit 36, 37, 38 and provide automatic gain control as disclosed in Specification 709,038, [Group XL (c)]. The cathode potential of rectifier 16 maintains the grid-cathode path cut off between synchronizing signals so that the circuit is largely unaffected by noise pulses. Noise pulses having amplitudes exceeding the amplitudes of the synchronizing pulses are amplitude limited by grid current flow in grid resistor 27.
